Abstract
Remote health care monitoring, a system that allows hassle-free monitoring of human health outside healthcare facilities, has been envisioned to revolutionize healthcare sector. New generation nanosensors of impeccably small size, better biocompatibility, wireless connectivity, memory, and automated decision-making ability are being developed for life-supporting implants, preventive measurements, long-term monitoring, and delivery of medication to diseased people. Wireless connectivity and cloud storage allow remote healthcare by enabling users to upload and access health data at locations well beyond the clinics and obtain interventions. These transformative advancements hold immense potential to improve the quality of healthcare by assuring better assessment, assistance, and treatment while also eliminating the invasive and costly diagnostics, and distance barriers in medicine to give patients the freedom of comfort and mobility. This chapter discusses the current state-of-the-art in the area of smart wireless sensors for human healthcare. Data transmission techniques and recent advancements in both smart wireless wearable and implantable nanosensors systems are highlighted. Few exemplary smart programmable devices of biomedical applications are also discussed. Finally, major challenges such as device sensitivity, accuracy, repeatability, and patients security and privacy concerns that may affect the effective utilization of smart wireless sensors in healthcare applications are discussed.
